Phase 2 of epic #4636, absorbing #4327 and #4354. Implements ADR-4650 decision 3: containment is a boundary concern — the predicate runs where external input enters, not at whichever interior call site remembered. Four boundaries now validate against their managed root and reject with a USAGE-shaped error before touching the filesystem: todo complete <name> -> todosDir(cwd) check predicate --phase-dir <dir> -> projectDir check decision-coverage-plan <dir> -> projectDir (via resolvePath) check gap-analysis.plan-post <dir> -> projectDir #4327 understated its own severity. It reports that a traversal name "resolves outside the todos root", which reads as an information leak. Measured, it was destructive: the command exited 0, MOVED the outside file into completed/, and unlinked the original. cmdTodoComplete ends in fs.unlinkSync(sourcePath), so an unconfined name consumed across the boundary rather than merely reading across it. Validation now precedes every fs call — existsSync, readFileSync, ensureDir, writeSync, unlinkSync — and both halves of the move are confined, so neither source nor destination can land outside the root. --dry-run is rejected on the same terms; a preview must not leak a resolved outside path either. #4354 reproduces exactly: a BLOCKING gate returned block:false sourced entirely from a SECURITY.md in a caller-chosen directory outside the project. THE HARDER HALF, found by the isolated adversarial review of the first attempt: validating a path and then using a DIFFERENT one closes nothing. The first fix validated `--phase-dir` joined against `--cwd`, then passed the RAW unjoined value into the predicate context. gate-predicate-evaluator uses it as-is and findPhaseArtifact resolves a relative path against the REAL process cwd — so validation and the read used two different roots whenever process.cwd() differed from --cwd. Reproduced: running from a directory holding a plan with `secret_field: LEAKED_VALUE`, a predicate declared against an empty --cwd project exited 0 and returned "actual":"LEAKED_VALUE". The rule now applied at all three router sites: **use the validated resolved path, never the raw input.** Independently re-verified after the fix — the lookup resolves in the --cwd project and no value leaks. gate-predicate-evaluator.cts is untouched and still imports no fs. Confining in the router is what keeps that pure-leaf contract intact AND covers ${PHASE_DIR} interpolation into command-exit-zero, which an evaluator-local fix would have missed entirely. Also fixed, same review: `todo complete .` and `..` passed containment (they resolve to the pending dir, which IS inside the root) and then threw an uncaught EISDIR with an absolute-path stack trace. Now a clean USAGE rejection naming the real reason — "todo name is not a file" — rather than borrowing the escape message, which would have stated something false. Ripples discharged BEFORE the verification checkpoint rather than after, per the Phase 1 retrospective: docs/reference/gate-predicates.md and docs/CLI-TOOLS.md document the new constraints, CONTEXT.md records why containment lives at the router rather than the evaluator, the changeset is written, and the install-tree goldens were regenerated to confirm unchanged (no new shipped file) rather than assumed.

Changeset Fragments
This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.
Why
Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.
See #2975 for the full rationale.
Adding a fragment
node scripts/changeset/new.cjs \
--type Fixed \
--pr 1234 \
--body "fix the thing — explain the user-visible change in one sentence"
This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.
Format

type: Fixed

**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.
Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.
Opting out
PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.
At release time
Promotion is automatic. The release workflow's finalize job runs:
node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD --allow-empty
This reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, and deletes consumed fragments. The --allow-empty flag ensures a no-change release still gets a dated heading (with a _No notable changes._ placeholder). A subsequent verify step confirms the promotion landed correctly. Maintainers do not run this by hand.
Archived fragments
.changeset/archived/ holds fragments for already-shipped releases (≤ 1.3.1), retained for provenance. Their content was hand-curated into the dated ## [1.x.y] sections of CHANGELOG.md during the #690 backfill — they were never consumed by render. All changeset tooling enumerates .changeset/ non-recursively, so archived fragments are never picked up or rendered. Do not move them back to the top level.
